Description

Technical Field

[0001] The present invention relates to an underwater high-energy variable light field adjustment and control device, which is mainly used for high-energy active illumination of underwater ultra-high-speed moving target imaging, and belongs to the field of underwater lighting technology. Background Art

[0002] Generally speaking, in a closed water shooting range, an optical high-speed imaging intersection measurement method is used to measure the ballistic parameters of ultra-high-speed projectiles. For optoelectronic imaging devices, light is a necessary condition for imaging. Especially in an ultra-high-speed underwater shooting range where the test space is completely enclosed for safety reasons, the high-speed imaging system needs to complete exposure within an integration time of 0.02 ms. Considering that the object distance for shooting is generally about 4-5 meters, due to the strong absorption and scattering effects of water on light waves, the light is severely attenuated when propagating in water. However, it is necessary to ensure that the object-side illuminance must be controlled above 5000 Lux in order to form an image-side illuminance above 1 Lux in an underwater high-sensitivity high-speed camera, and there is a higher requirement for illuminance to increase the frame rate and integration time of the camera to improve the interpretation and calculation accuracy of the underwater ballistic parameters of the ultra-projectile as much as possible.

[0003] The light efficiency of the underwater light field created will directly affect the imaging clarity, system detection distance, and detection range of the underwater optical measurement system. Ordinary light sources have a fixed light field because of their fixed placement position, depth, and beam angle, and thus cannot be adjusted. They cannot provide the object-side illuminance that can complete clear imaging for ultra-high-speed moving targets at the moment when the shutter of the high-speed camera is opened under different test conditions, different navigation depths, and different object distances.

[0004] Therefore, when using a high-speed imaging method in a closed water shooting range, it is necessary to use a high-energy variable light field to actively illuminate the ultra-high-speed moving target. Summary of the Invention

[0005] In view of the many defects and deficiencies in the above background art, the present invention has made improvements and innovations. The purpose is to provide a device that can quickly create a uniform light field with a variable illumination area underwater according to the test requirements, so as to ensure high-intensity continuous illumination within the integration time of the high-speed camera.

[0006] Another object of the present invention is to provide an underwater uniform object-side illuminance of not less than 5000 Lux for the full-frame clear imaging of an underwater high-speed camera under different depths and different object distances underwater, so as to achieve the precise processing of the optical imaging method for the ballistic parameters of underwater high-speed moving targets.

[0007] To solve the above problems and achieve the above object of the invention, an underwater high-energy variable light field adjustment and control device of the present invention is realized by adopting the following design structure and the following technical solutions:

[0011] As the further improvement of the present invention above, the slide rail (8) is a track with a gap in the middle formed by combining two L-shaped plate bodies arranged opposite to each other. The fixed end of the track is integrally connected to the cross bar of the mounting bracket (6) through a connecting rod.

[0012] As the further improvement of the present invention above, the lighting device (9) is formed by arranging a plurality of lighting device bodies coaxially. The lighting device (9) is connected to a pulley (11) through a connecting rod (10), and the pulleys (11) are symmetrically installed on both sides of the top of the connecting rod (10).

[0013] As the further improvement of the present invention above, the lighting device body includes a mounting rod (9a), a connecting piece (9b), a mounting plate (9c), a two-axis rotary pan-tilt (9d), and a lighting lamp (9e). Among them, the top of the lighting lamp (9e) is slidably installed at the bottom of the two-axis rotary pan-tilt (9d), the top of the two-axis rotary pan-tilt (9d) is installed at the bottom of the mounting plate (9c), the top of the mounting plate (9c) is installed at the bottom of the connecting piece (9b), and the top of the connecting piece (9b) is installed at the bottom of the mounting rod (9a).

[0014] As a further improvement of the present invention described above, the mounting rod (9a) is a telescopic adjustable rod. One end of the telescopic adjustable rod is a mounting portion, and the mounting portion is a square steel with a hollow interior. A fastening hole penetrating the front and back surfaces is provided at the free end of the square steel. The other end of the telescopic adjustable rod is a fixing portion matching the shape of the mounting portion, and the fixing portion is a solid square steel.

[0015] As a yet further improvement of the present invention described above, the connecting member (9b) is an integral flat square steel or a circular rod-shaped member; the mounting plate (9c) is an integral plate-shaped member. An installation groove is provided in the middle of the lower end of the plate-shaped member, and the two-axis rotary pan-tilt (9d) is installed in the installation groove through its engaging member; a long-shaped sliding groove is provided at the lower end of the two-axis rotary pan-tilt (9d), and the lighting lamp (9e) is slidably installed in the long-shaped sliding groove through its slider and the lighting lamp (9e) slides back and forth in the long-shaped sliding groove.

[0016] As a yet more further improvement of the present invention described above, the lighting lamp (9e) is composed of a lamp base (9e1), a lamp (9e2), a laser angle constraint mirror (9e3), a lamp cover (9e4) and a sealed waterproof cabin (9e5). Among them, the lamp (9e2) is installed in the middle of the lamp base (9e1), a laser angle constraint mirror (9e3) is provided on the periphery of the lamp (9e2), the lamp cover (9e4) is hermetically connected to the lamp base (9e1) to enclose the lamp (9e2) and the laser angle constraint mirror (9e3) inside the lamp cover (9e4), and a sealed waterproof cabin (9e5) is tightly connected to the bottom of the lamp cover (9e4).

[0017] As a still more further improvement of the present invention described above, an anti-rust layer, a waterproof layer and a warning layer are sequentially sprayed from the inside to the outside on the outer surfaces of the lifting mechanism (5), the mounting frame (6), the underwater mirror (7) and the lighting device (9), and fluorescent powder is applied on the warning layer.

[0018] The working principle is as follows: Before using an underwater high-energy variable light field regulation and control device with the above-described design structure, it needs to be installed for standby.

[0019] During installation, first, the lighting lamp (9e) is independently assembled at the production site, and the overall assembly of the lamp base (9e1), the lamp (9e2), the laser angle constraint mirror (9e3), the lamp cover (9e4) and the sealed waterproof cabin (9e5) is completed to form a lighting lamp (9e) that can be independently packed and transported.

[0020] Then, at the test workshop, the lighting lamp (9e) is assembled with the mounting rod (9a), the connecting member (9b), the mounting plate (9c) and the two-axis rotary pan-tilt (9d) as required to form an independent lighting device body and stored in the workshop.

[0021] In the test phase, multiple independent lighting device bodies are connected to pulleys (11) through connecting rods (10) in the test site according to the standard requirements. The pulleys (11) are symmetrically installed on both sides of the top of the connecting rod (10) to form a complete lighting device (9).

[0022] After that, the fixed end of the slide rail (8) is connected to the cross bar of the mounting frame (6) as a whole through a connecting rod according to the standard requirements.

[0023] Subsequently, an array of lighting devices (9) is electrically connected to the synchronous controller (1) and the LED light source onshore drive control cabinet (2), and at the same time, the underwater light field illuminance measurement device (3) and the onshore data acquisition device (4) for illuminance are electrically connected.

[0024] Finally, after the adjustment of the corresponding depth in the water target track is completed by controlling through the lifting mechanism (5), the array of lighting devices (9) can be powered on for operation.

[0025] During use, in the actual use process of the long box-type water target track of the present invention, the onshore drive control cabinet, the synchronous controller, and the onshore data acquisition device for underwater light field illuminance measurement are arranged onshore. The underwater light field illuminance measurement device (4), the lifting mechanism (5), the underwater mirror (7), the slide rail (8), and the lighting device (9) are arranged underwater, and the lifting mechanism (5) and the mounting frame (6) are installed on both sides of the pool wall across the water target track (12).

[0026] The hydraulic lifting mechanism can complete the movement of the load-bearing slide rail type trestle where the overall lighting device (9) is located in the underwater depth direction of the water target track by using the special track and hydraulic lifting device across both sides of the pool wall of the water target track. On the premise that the depth safety of the ballistic trajectory can be guaranteed, the installation height and irradiation distance of the lamp group are reduced as much as possible to ensure the underwater light field intensity. If necessary, the lamp group can even be completely lifted out of the water for lighting and long-term storage.

[0027] The underwater light field illuminance measurement and onshore data acquisition device is a measurement device composed of multiple underwater illuminance sensors, which is used to measure whether the actual illuminance at each position and angle within the underwater irradiation range of the device can meet the technical requirements, and accordingly, the angles and positions of the underwater mirror group and the mirror angles of the device are adjusted adaptively. The underwater light field illuminance measurement device (4) is installed at a fixed underwater position, and its installation axis, position, and attitude can be accurately measured, which is used to calibrate the position of each illuminance sensor. The illuminance and attitude measurement data of the sensor can be transmitted to the onshore data acquisition device of the underwater illuminometer in real time.

[0028] The present invention can achieve the adjustment of the underwater light field irradiation range, intensity, and irradiation area. The methods adopted are as follows: the lateral adjustment of the LED lamp group target track position can complete the adjustment of the underwater irradiation area; the hydraulic lifting mechanism adjustment of the slide rail pool wall can complete the adjustment of the underwater light field irradiation range and light field intensity; and the underwater mirror group and angle adjustment can both complete the adjustment of the underwater irradiation area and the adjustment of the underwater light field irradiation range and light field intensity. In this way, multiple adjustment methods can be used for compound adjustment according to the test requirements of high-speed optical imaging.

[0029] In the present invention, the LED lamp group or the lamp group both refer to the lighting device (9).

[0030] Finally, as time goes by, after the present invention is used up, it needs to be recycled. When recycling, first cut off the power supply, lift the array of lighting devices (9) out of the water through the lifting mechanism (5); then disconnect the electrical connection with the drive control cabinet (2); disconnect the connection relationship between the slide rail (8) and the mounting frame (6) through the connecting rod; then restore the complete lighting device (9) to the independent lighting device body by disconnecting the connecting rod (10), and finally clean and repair its various components and transport them to the workshop for storage, waiting to be used for the next cycle.

[0031] The beneficial effects of the present invention compared with the prior art are as follows:

[0032] 1. By changing methods such as the position, depth, and irradiation distance of the LED light source, the present invention can create an underwater light field with different lighting ranges and irradiation intensities in different test areas of the water target track, can continuously provide an underwater object-side illuminance of not less than 5000 lux, and can effectively solve the bottleneck problem of high-speed imaging illumination for ultra-high-speed moving targets in a closed water target track.

[0033] 2. The present invention can be adjusted according to actual needs, and can provide an object-side illuminance that can achieve clear imaging for ultra-high-speed moving targets at the moment when the high-speed camera shutter is opened under different test conditions, different navigation depths, and different object distances.

[0034] 3. The present invention adopts underwater small-angle high-frequency high-energy blue-green LED lighting, light-emitting angle control, and underwater depth range rapid movement technology, and can quickly create a uniform light field with a variable irradiation area underwater according to the test requirements, ensuring high-intensity continuous lighting within the integration time of the high-speed camera.

[0035] 4. The present invention can provide an underwater uniform object-side illuminance of not less than 5000 Lux for full-frame clear imaging of an underwater high-speed camera under different underwater depths and different object distances, realizing the precise processing of the optical imaging method for the ballistic parameters of underwater ultra-high-speed moving targets.

[0036] 5. The exterior of the present invention is coated with anti-rust paint, thus preventing rust and extending the service life of the entire device, achieving environmental protection and saving resources. At the same time, a fluorescent material that can emit light by itself is coated on the exterior of the device, which can clearly indicate the position of the wire laying device at night, in a dark room or in an underground construction environment, effectively playing a role in safety reminder, improving visibility, being easy for people to distinguish, and increasing safety in construction and daily life.
